This Order declares that imported “plant activator” with a basis of acibenzolar‑S‑methyl (tariff classification 3808.99.00) is to which the Part III Schedule 4 tariff item applies, effective 23 June 2008 (made under s.269P of the Customs Act 1901).
Practically, importers can claim the Schedule 4 tariff treatment for that product until the Order is revoked under ss.269SC or 269SD or an explicit end date; the measure relies on correct tariff classification and executive discretion to create or remove the concession.
